Chapter 1 – AT Commands, S-Registers, and Result Codes

Modulation Handshake

Sets the modem protocol for handling handshake negotiation at connection time if
the communication speed of the remote modem is different from the speed of the
ATN<value>
0 Modem performs handshake only at communication standard specified by S-
Register S37 and the B<value> command.
1 Modem begins handshake at communication standard specified by S-Register
S37 and command B. During handshake, fallback to a lower speed can occur.
1
OK if <value> = 0 to 1
ERROR if <value> ≠ 0 to 1.

Return Online to Data Mode

Exits online command mode and enters online data mode. If the modem is not in
online command mode when this command is received, the modem generates an
ERROR result code.
ATO<value>
0 Exits online command mode and returns to data mode.
1 Issues a retrain before returning to online data mode.
3 Issues a rate renegotiations before returning to online data mode.
0
CONNECT if <value> = 0, 1, 3 and result code and call progress monitor are set to 0
(X0).
CONNECT <rate> if <value> = 0, 1, 3 and the result code and call progress monitor
are not set to 0 (X<value> where n = 1 to 7).
NO CARRIER if the connection is not successfully resumed.
ERROR if <value> ≠ 0, 1, 3.

Set Pulse or Tone Dialing Default

Configures the modem for pulse (non-touch-tone) or Tone dialing. All subsequent
D<dial_string> commands use pulse dialing until either the T command or a tone
dial modifier is received by the modem. Tone dialing is the default setting. This
command does not use parameters and generates an ERROR result code when
parameters are attached to the command.

Result Codes Enable/Disable

Result codes are informational messages sent from the modem and displayed on the
monitor. Basic result codes include OK, CONNECT, RING, NO CARRIER, and
ERROR.
Use the Q<value> command to enable or disable result code generation by the
modem. If result codes are disabled and an invalid parameter value is entered, the
modem does not generate an ERROR result code because result codes are turn off.
ATQ<value>
0 Enable result codes.
1 Disable result codes.
0
OK if <value> = 0 to 1
ERROR if <value> ≠ 0 to 1.
